Su Yao is the eldest daughter of Duke Dingguo, and she was regarded as the pride of the family when she was born. She has been smart since she was a child, and is proficient in music, chess, calligraphy and painting, and is highly praised by her family and the outside world. At a palace banquet, Su Yao met the prince Xiao Yichen, and the two had a good impression of each other. However, the good times are always short-lived. The Duke of Dingguo was framed by a traitor and his family was destroyed overnight. Su Yao also went from being the eldest eldest daughter to being a prisoner, suffering all the humiliation.
In prison, Su Yao got acquainted with a mysterious old man. Seeing that she had extraordinary talents, the old man taught her peerless martial arts and strategic skills. Su Yao relied on her perseverance and talent, studied hard, and finally escaped from prison with the help of the old man.
After escaping from prison, Su Yao changed her name to Su Yue and began her own path of revenge. She first relied on her medical skills to enter the largest medical clinic in the capital and became a highly praised female doctor. In the medical clinic, Su Yao met many dignitaries and accumulated rich network resources for herself.
By chance, Su Yao learned that the masterminds behind the frame-up of the Dingguo Palace were actually the second prince Xiao Yixuan and his sister Su Wan. In order to take revenge, Su Yao decided to get close to Xiao Yixuan and look for opportunities to expose his crimes. In the process of approaching Xiao Yixuan, Su Yao and Xiao Yichen met again. At this time, Xiao Yichen already knew Su Yao's identity. He felt sorry for what Su Yao had suffered and decided to help her get revenge.
With Xiao Yichen's help, Su Yao gradually mastered the criminal evidence of Xiao Yixuan and Su Wan. At a palace banquet, Su Yao exposed Xiao Yixuan and Su Wan's crimes in public, causing an uproar.
